NOAA Releases New Views of Earth's Ocean Floor
fishmike writes "NOAA has made sea floor maps and other data on the world's coasts, continental shelves and deep ocean available for easy viewing online. Anyone with Internet access can now explore undersea features and obtain detailed depictions of the sea floor and coasts, including deep canyons, ripples, landslides and likely fish habitat. The new online data viewer compiles sea floor data from the near shore to the deep blue, including the latest high-resolution bathymetric (sea bottom) data collected by NOAA's Office of Coast Survey primarily to support nautical charting."
First! Seriously cool stuff though. As most geeks here will know, we know more about outer space than we do our own oceans. Every new little bit of detail we get is just more and more fascinating as it knits the bigger picture together.
...it is shown in Google Maps? More to the point, how long before long, straight stretches of seabed start to affect driving directions?

It seems to work much the same way Google Maps/Earth, except that you can dial in different data overlays like : Fishmaps, Geological maps, Hazards (Tsunamis, Earthquakes, Volcanoes). Quite neat. And probably very useful if you are a scientist/academic studying this kind of data.
Why did the chicken cross the road? Because Elon Musk put an AI chip in its head.
to avoid upsetting them, I fully expect the location of Ry'leh to be blurred....
Can we really trust liberal big government scientists to give us an unbiased view of the ocean floor? I just think we should wait until all the facts are in before we take their word for it.
Talking about the long horizontal squiggly lines on the ocean floor which are visible from outer space (eg zoom out google earth), would any oceanology be so kind to explain in layman's terms how these were formed? Meteorites? Or just give me the official name so I can wiki it ;-)

So that's where Atlantis is.. -24.400, 31.360 - thanks!
They're called ship tracklines. They are the path of the ship that made the bathymetry (water depth) survey. Generally speaking, there is broad, low-resolution bathymetry from all the world's oceans. It is derived from satellite gravity measurements. On top of that there are "groundtruth" surveys conducted by ships with fathometers to measure the ocean depth. Inevitably, these differ by a slight amount from the lower-resolution data. Ship tracks will have a variety of geometries, but if you are trying to cover a specific area, a grid-like geometry is common. Put those more precise values into the lower-resolution grid and you get interesting-looking patterns that have nothing to do with the actual sea-floor bathymetry. They just represent the places the ship traveled.
Horrible map. It's got a whole bunch of squiggly lines all over it!
Oh, that's just a grammar problem. The squigglies won't show up when you print.

Maybe a certain Mr Schettino could make use of this data when buzzing coastlines :p
(His claim that he hit uncharted rocks is actually true when looking at one of the old and coarse UK bathymetry datasets)
It's nice to see some of my work come to light. I created prototypes for this back a few years ago with Google Earth and GDAL for the Bathymetric Attributed Grids (BAG) file from Hydrographic Surveys... http://youtu.be/7fOTlqqQ5O4 Or build a visualization yourself using the code: https://github.com/schwehr/bag-py
